Power supply method and device

Abstract

The invention embodiment provides a power supply method and device. The power supply device comprises the following structures: a detection module connected with a detection pin group of a camera head module and used for generating identification signals according to the detected detection signal on the detection pin group of the camera head module; a power supply identification module connected with the detection module and used for identifying the model of the camera head module according to the identification signal, thereby determining power supply information corresponding to the model of the camera head module; a power up control module respectively connected with the power supply identification module and the power supply module, and used for controlling power supply sequence of at least three power supply units of the power supply module and power supply voltage of each power supply unit according to the power supply information, thereby enabling the at least three power supply units to provide power for the camera head module. The power supply method and device are used for providing power for different model camera head modules used by user equipment in a self-adaptive manner.

Description

technical field [0001] Embodiments of the present invention relate to power management technologies, and in particular, to a power supply method and device. Background technique [0002] With the development of the integration technology of user equipment such as mobile phones, the number of cameras configured on the user equipment has also gradually developed from one to two. [0003] The cameras configured on the user equipment all need multiple power supplies, but due to the development of camera technology, cameras with different sensors have different power-on sequence requirements for the multiple power supplies they need. Considering that the resources of the platform used by the user equipment are limited, each power supply cannot be powered independently. Therefore, for each camera with different sensors, the power circuit in the platform needs to be individually designed to match the power-on sequence of each power supply. [0004] During the development or produc...

AI Technical Summary

Problems solved by technology

[0004] During the development or production of user equipment, because the configured camera may be upgraded or replaced, if the power-on sequence of each power supply of the replaced camera is different from that of the original camera, the user must redesign the Power circuits on device platforms, resulting in extended development or production cycles
